To all whom it may condom:

Be it known that 1, PAUL Fnnreene, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Methods of Packaging Merchandise, of which the following is a specification.

The hereinafter described invention relates to an improved method of packaging perishable merchandise, such as. cofiee, tea, prunes,raisins and tobacco andsimilar dryarticles in order to preserve the full'flavor or the commodity and prevent the same" from becoming afiected in any manner whatsoever by moisture or climatic conditions, while at the same time protecting the contents of the package from deterioration of any kind whatsoever so 1011 as thepackage remains in its sealed con ition; the invention permitting perishable goods to be placed or sealed within non-metallic vessels for shipment and transportation with the assurance that full protection will be given the contents thereof until such times as the package is opened. p

In carrying out the invention the commodity to be merchandised or packaged is primarily enveloped within a moisture proof lining in order to protect thesame against absorption of the moisture :con-' tained' therein. This lining or casing is preferably applied to the goods prior to the placing of the same within the casing or envelop, which is composed of an inner .fibrous liner and outer fibrous lining, there being interposed between the said inner and outer lining a metallic lining. This inclosing envelop has the ends thereof folded down to partially seal or envelop the merchandise, the final laps of the interfolded.

ends of theenvelop being pasted down or sealed inthe usual manner to secure the ends of the package closed. "After the merchandise has been inclosed'or sealed within the package as described, the closed ends thereof are hermetically'sealed by means of suitable end pieces which are united to the closed end of the-package by an adhesive being applied under. pressure so as tojfirmly compoundgimpervious to moisture, the ends sea or mbe th same o a to speak, withpositioned 'for scam .held within a suitableclamp or form mold which protects theside walls of the package against bursting or breaking by reason of the end pressure brought to bear against the contents thereof. y

For a full understanding of the invenf tion, reference should be had to the'accompanying shwtbf drawings, wherein,

Figure]; is a broken erspective view of the packagewith its sea ed contents.

. Fig. 2 is a perspective view of one of the sealing ends'separated from the package.

Fig. 3 is a broken detailed view of the package with one of its ends open and with the contents removed therefrom.

Fig. 4 is a broken perspective view illustrating the ackage to be sealed within a forming mo (1 and with' the hermeticends In the drawings, tfie numeral 1, is used to designate the innernon-absorbent liner for the package and which embraces or incloses the goods to be packaged, and 2, the

nner fibrous liner forthe packing envelop proper and which lies incontact with the erably formed of fibrous material and there is interposed between the inner liner wall 2, and the outer wall covering 3, the metallic layer orliner 4, preferably formed of sheet lead. .These membersare arranged in the. usual form of a side sealed envelop, the ends thereof intertolded inthe manner similar to any package envelopadapted to sin round or embrace merchandise to be Packaged.

The sealing ends 5 of the package are preferably formed of heavy card board and are provided with' the beveled edges 6. In the ;lnner non-absorbent liner 1." The outer wall or covering 3 of the packing envelop is pref;

said ends are then properly positioned to cover the ends of the package and then subjected to pressure or rather pressure is placed endwise to the package while the ends '5 are applied thereto, so as to press the ends 5 firmly to a secure seat, this end pressure embedding the ends 5 so'to speak, wlthin the surrounding edges of the ends of the package, the a lied pressure securely and evenly distributing the adhesive compound applied to the under face thereof, and the said pressure maintained for approximately two or three minutes or until the impervious adhesive compound is thoroughly dried. During this pressure applying operation, the package w1th the contents inclosed therein is held within a suitable forming mold 7 while the pressure plates 8 are brought to bear onto the applied ends 5, which said mold prevents the end pressure applied for the sealing of the ends 5 from causing a bursting or tearing apart of the walls of the package, Which otherwise would occur on the severe endwise strain to which the contents thereof are subjected on the pressure being applied, or, which if it did not cause a rupture of the walls of the package would at least cause such a bulging thereof as to prevent an attractive appearance to the sealed package.

T have found that perishable merchandise when packaged in the manner set forth is rendered impervious to moisture even when placed within water for a number of hours, 111 fact, cofi'ee so packaged has been submerged within water at a temperature of 125 degrees Fahn, and maintained so submerged for a period of over 20 minutes and on the removal thereof from the bath the package opened and the contents thereof found to be in perfect condition. Prunes so packaged were submerged in water at a temperature of 75 degrees Fahr. and maintained so submerged for a period of one hour and a half, and after removal and opening of the package the contents thereof found to bein perfect condition, and tobacco so packaged as beensubjected to similar tests with the result that the contents of the package were In no manner whatsoever afiected by the water.

By the described method of packaging the goods, the same are placed in condition for easy and ready handlin and shipment, and shipment is ren ered less ex ensive suc than where the merchandise is seale within hea metallic containers.

It wi 1 be noted that on the sealin ends 5 being applied, that there is formed etween the end flaps of the package and the side walls thereof, and the under face of said ends a layer 9 of the adhesive material impervious to moisture and inasmuch as the side walls of the envelop arerendercd moieessee? interposed between the inner and outer linmg or covering of the envelop or package that on the ends 5 being properly applied thereto under pressure, there is formed a. perfect hermetic seal for the closed ends of the envelop, and the same thus rendered moisture proof during such times as the package remains in its sealed condition.

The described invention will appeal to those desirous of lacing their merchandise before the public in such a manner that deterioration thereof ,cannot take place at any time prior to the opening of the ackae and this irrespective as to whether t e pact age may be subjected to moisture or not, inasmuch as the aromatic flavor of the goods is maintained and the goods presented to the customer with the full freshness andfiavor possessed thereby prior to the packaging thereof. 7

If so desired, the outer coverin 2, of the envelo may have applied to the inner face thereo a coating of parafin, but such is be lieved to be unnecessary'where the metallic liner wall is is employed and introduced between the inner and outer walls 1 and 2 of the envelop. The essential feature of the invention resides in the hermetic sealing ends 5, with the impervious adhesive applied betweenthe inner surface thereof and the exterior surface of the final lap of'the ends of the envelop, inasmuch as it isothese ends with the impervious'adhesive applied 1. The method of packaging .erishabh merchandise, which consists in incosing the same within an envelop formed of 1m; :rer and outer wall covering separated hy a moisture proof liner interposed therehetween interfolding the ends of the package over the goods placed therein, and applg under pressure to the ends so closed hermetic sealing ends having introduced be tween the under surface thereof and the guter surface of the. ends of the package an impervious adhesive and mainta the ends under such applied pressure until the adhesive becomes dried. V

2.. The method of packa 1;; perishable merchandise, which consists in first inclos= iIlg the article within a non-absorbent wrap= ping, thence placing the same within a moisture proof envelop having an inner d an outer wall coverin separated loy a cis time proof as; an the ends masses of the envelop to inclose the wrap ed oods, thence hermetically seeling'the c ose ends by applyin thereto under pressure sealing end pleces aving a coating of an im ervious adhesive applied to the under sur ace thereof and maintaining the same under pressure until the adhesive becomes dried.

. In testimony whereof I have sied my name to this specification in the pnce of two subscribing witnesses.
